About the ERS-RB01 RPM-BLDC Telemetry Sensor
Precision RPM Feedback With Seamless Integration
The ERS-RB01 measures brushless motor RPM with high accuracy by connecting directly to two ESC output wires, ensuring reliable real-time data capture. Using the CRSF interface, it transmits this information to a compatible ExpressLRS receiver, which then relays it to your EdgeTX radio for live monitoring. Its compact, lightweight design makes installation simple, while pass-through ports allow multiple sensors to be daisy-chained for expanded telemetry setups. With plug-and-play compatibility and support for multi-unit monitoring, the ERS-RB01 is ideal for a wide range of RC and robotics applications.
